Offering a broad range of interior furnishings and decorative collectables the auction will comprise over 300 lots. Presenting connoisseurs, interiors designers, and private collectors with the chance to buy wonderfully quirky and interesting historic objects of natural history, the sale will also include items for decorating the home – from carpets, to lighting, furniture and decorative objects. Standing at over four and a half feet high, the enormous Tarbosaurus leg illustrated above centre comprises three main bones, stretching from the three toes, up to the pelvis of the dinosaur. Pre-dating its famous North American relative the Tyrannosaurus rex the two bear many similarities, despite roaming the earth around two to five million years apart.

The sale also includes one of the world’s largest ever eggs illustrated above left that of the giant elephant bird. Measuring 27.5 inches in circumference and standing 12.5 inches tall the egg is over 160 times the volume of the standard chicken egg. The elephant bird or Aepyornis maximus, is known to have become extinct during or prior to the 17th century. Similar in appearance to the ostrich, yet with a height of up to three metres it remains the largest species of bird to have ever existed.

A pair of double curved Mammoth tusks once belonging to a sub-adult Mammuthus primigenius measure 55 inches from root to tip illustrated above right. Dark in colour, apparently due to the diet of this particular mammoth, a complete pair has not been offered at Christie’s in recent memory. A single tusk sold at Christie’s South Kensington in September 2011 for £7,500.

A large fish fossil, or Diplomystus dentatus, discovered in the Wyoming desert by a ‘fossil hunter’ is also on offer (estimate: £3,000-5,000) illustrated above, alongside a selection of colourful ammonites illustrated below. Excavated by the present owner the fossil is approximately 50 million years old and has never been sold before. It is offered with full location information.
